Abstract

The Invention relates to a mobile cabin with a ventilation system and a method for ventilating it. The cabin has sound-absorbing properties, and the cabins can be connected to each other as modules to form a larger cabin unit using connecting means. The cabin ventilation system comprises at least one ventilator in the external part of the cabin ceiling, at least one air inlet passage and air inlet in the internal part of the ceiling, and at least one air outlet in the lower part of the cabin. The air inlet passage is straight-line and one-channel, and a labyrinth is formed in it with the help of sound-absorbing devices. The air outlet is located inside the cabin on the edge of the side wall panel of the floor and extends between the floor and the side wall panel under the floor of the cabin. The cabin back panel and front panel are detachable and comprise cover strips with magnets. There are adjustable support legs and 360° rotating wheels under the floor of the cabin in such a way that a gap is formed between the cabin and the ground surface of the room for the air to be expelled from the cabin through the air outlet. The method according to the invention describes directing air through such a cabin.
